  • Networking
Contacting partners, associated organizations and experts
Oho cs1 mFC 93DW XQ-0017.jpg
During the initial stages of this project, we were able to contact the channel Opensourcelowtech and exchange some ideas, for which we are very grateful
Initially, work was done on a replica of one of their project, which served as experience for this case

4 Development and documentation

Plans and specifications of all parts and components

  • Analisis of functions & structures
Oho cs1 006.jpg
Analysis of functions, assemblies and components
A review of the most important technical aspects in the design of this equipment was carried out, managing to identify and select its components, as well as its operating principles
  • Technical solutions
Development of technical solutions for assemblies and parts
A review of the different options adopted in the DIY machines was carried out to meet each design requirement, observing the following variants for some evaluated details:
* Evaluated detail: Type of collector
  • Parallel tubes
  • Zigzag tubes
  • Parallel plates
  • Spiral tube
* Evaluated detail: Material in contact with water
  • Copper
  • PVC
  • Steel
  • Galvanized iron
* Evaluated detail: Number of water circuits
  • Two circuits (coil heat exchanger)
  • Single Circuit (Mixed Flow Heat Exchanger)
See related comments: Discussion
Oho cs1 sol1.jpg
Additionally, Some guidelines were proposed to ensure the proper functioning of the equipment:
* Universal unions on manifold and tank connections
* Float and fisherman tube in the tank make-up water inlet
* Non-return valve in the collector water inlet
* Modular support structure, to maintain the height of the tank and allow the installation of the collector with different angles of tilt
  • Technical documentation
Creation of plans, parts lists, assembly instructions
Once all the necessary information was available, the project plans were prepared
  • Peer-Reviews
Peer-Reviews by the community, team members, experts etc.
A previous review stage was not carried out, but the technical observations were left for the formal certification stage, which is shown below.

5. Manufacturing, tests and improvements

To date, this project is on hold for manufacturing.

6. Certification DIN Spec 3105

  • Formal audit
Pdc certification-process-diag-page1.jpg
Verification of the completeness of the documents:
* Parts list
* Drawings of all parts and assemblies
* Assembly instructions
* Optional documents, technical notes
* These formal aspects have been verified, the project meets them satisfactorily
  • Assignment of reviewers
    Search and assignment of peer-reviewers with sufficient expertise:
  • Peer-reviews
    Realization of the peer reviews, technical clarification, improvements:
In the Parts list section, necessary comments and discussions have been made by the assigned reviewers and the developer
  • Certificate
    Issue of the certificate:
